WASHING MACHINE Filed July 10, 1950 parts such as Patented Dec. 9, 1930 JOHN H. DRAPER, or olmro a iuassaonusn rrs Y WASHING nlicrrrnn Application filed July in,"

This invention relates to machines forwashmg articles such as clothing and housea hold fabrics, and has particular reference to mechanism for continuously and alternately 5 immersing and squeezing the articles.

One of the objects of my invention is to provide a machine having an endless series of pockets for the articles, said series being flexible throughout and mounted to travel between squeezing rolls and through a bath of cleansing fluid.

Another object is to provide such a ma-' chine in which the collections of articles will pass between the squeeze rolls in overlapping .15 succession, whereby excessive parting and closing of the rolls will be avoided.

With the above objects in View, and others such as will be referred to, the invention con- Similar reference characters designate similar parts or features in all of the views.

A suitable tub or tank is illustrated at 10,. said tub having brackets 11 for the shafts of f squeeze rolls 12, 13, said shafts having gears 14. The parts or members of the machine so far referred to may be of any well-known or preferred structure, and the rolls maybe driven by any preferred power.

My invention relates to the means whereby the articles to be washed are subjected to re f peated immersions in cleansing liquid in the ations by the rolls. Said means consists of a flexible endless belt having pockets for.

holding collections of goods to be cleaned Such a carrier, broadly, is not new.

5c in carrying out my invention I utilize rope tub or tank, alternating with squeezing opers .1 f e. P c e s iac o s hecarr n b lt a n,

netting material such as that employed for fishnets or selnes. To construct the carrler or belt 1 fold awide strip of netting 15 at -its mid-width 16 (Fig. 4) and' secure the selvages 17 together, preferably, but-not neces} sarily by cord knotsi18. Such strip of doublednetting may be ofany length desired, according to the capacity wantedfor the machine. The two ends of .thefolded strip are connected by suitablemeans such as ,bytying together the pieces of loose rope. or

cord: at. the endsof the folded strip, thusmakling the net carrier endless. -In-practice, this endlesscarrier of nettingis usually longer in proportion co-the size ofa-the pockets presently described, than illustrated in Figures 1 straight rows across thebelt, theoperation hereinafter described, would he interfered with by the diiferencesfin.thlckness of the loadedpocket portions of thebelt when passing between the squcezer'olls gTherefore,an

important feature of .my .invention resides in providing the belt with pockets having a staggered relationship to eaoh other, so that although thebelt as a whole has a plurality of longitudinalrows ofpockets, no twopockets will arrive simultaneously at theibite of the squeezerolls A In-some stl uctures. included within the scope of my invention, the pockets maybe 1 made of material separate from thejbelt and attached thereto .in staggered relationship. In the embodiment of the invention illustrat ed, however, said 5 pockets; are. provided .in a

-simple and efl'fective manner; bycord-tying together the two layers of the belt netting along somewhatll-shaped lines indicated at .-19,-in the proper locations other. than directly side by side, such as illustrated, andslitting the outermost layer of, the netting on lines meetingtheupper ends of the U-shaped tied lines, such slits then providing openingsQO through which articles can be inserted into the pockets between the 7, two layers of. the belt netting, As illustrated byFiguresQ and 4:, theidescribed tying at 19, and slittingat 20 is effected in suchlo'cations thattheresult- V staggered relationship. The described method of providing the pockets, byjsuch tying at 19 and slitting at 20, constitutes another important feature of my invention, whether the relative positioning of the pockets is staggered or not.

While it is convenient to make the belt of a wide strip of'netting and folding it at its mid-width, I do not limit myself thereto, as

it may consist of two strips of netting or similar flexible material, with the edge portions of the strips suitably connected;

I have illustrated the carrier belt' asde- '5 signature.

said strip being folded at its mid-width to provide inner and outer layers, the two layers being connected together in locations to form pockets in side by side staggered relationship and the outer layer having slits to give access to such pockets.

In testimony whereof I- have aifi-Xed my JGHN DRZQPER.

form of a plurality of loops instead of the single one illustrated.

When some or all of the pockets have been filled with goods to be laundered, the openings are closed by cordage knots 21 or any other preferred closing devices, and then the machine is'operated in the well-known way to causethe pocketed articles to be repeatedly immersed in cleansing liquid in the tub and be subjected to squeezing action by the rolls,

for as longa time as may be desirable.

It is not always necessary to close the openings at the tops of the pockets. For instance, when the articles to be cleansed are in bags ofnetting, such bags are not likely to slip out of the carrier pockets, especially if the loaded bags closely fit the carrier pockets." And while I consider it best to so arrange the pockets that'the openings needed to enable the articles to be inserted therein and removed therefrom shall be at the tops of the pockets on the rising portion of the belt,

' I do not limit myself thereto, as for some purposes, or for some classes of goods, it may be'preferred to provide vertical entrances to the'pockets so'that articlesmay be inserted verse'rows of pockets in side by side staggered ,or removed in a side-wise direction.
